What is AWS Architecture? Components Explained Using Diagram

Any government agency, organization, or company needs to host applications and secure and store data, including videos, photos, or any kind of information, at the minimum cost possible to reduce the workload and achieve a smooth working platform.

AWS, which stands for Amazon Web Services, comes up with cloud services to handle high web traffic and the huge amounts of data generated daily on applications or websites. The AWS cloud architecture ensures that customers are following best practices, guidance, and recommendations to develop and maintain cloud solutions.

Introduction to AWS Architecture

AWS is a beginner-friendly platform to use. We can easily create and deploy websites or any application here on AWS. It is also cost-effective as we only have to pay for what we use. There is no particular long-term contract or commitment for payments. Moreover, it provides high performance, availability, scalability, and security. AWS architecture plays a vital role in enhancing the overall performance of this platform for customers to use it to the fullest. So, they can choose AWS as their cloud provider without any doubt.

What is AWS Architecture with Diagram

Let’s now come to the AWS cloud architecture diagram.

AWS architecture diagram

The above diagram is a simple AWS architecture diagram that shows the basic structure of Amazon Web Services architecture. It shows the basic AWS services, such as Route 53, Elastic Load Balancer, EC2, security groups, CloudFront, Amazon S3 bucket, etc. By using S3 (Simple Storage Service), companies can easily store and retrieve data of various types using Application Programming Interface calls.

AWS comes with so many handy options such as configuration server, individual server mapping, and pricing. As we can see in the AWS architecture diagram that a custom virtual private cloud is created to secure the web application, and resources are spread across availability zones to provide redundancy during maintenance. Web servers are deployed on AWS EC2 instances. External traffic to the servers is balanced by Elastic Load Balancer.

We can add or remove instances and scale up or down on the basis of dynamic scaling policies. Amazon CloudFront distribution helps us minimize latency. It also maintains the edge locations across the globe—an edge location is a cache for web and streaming content. Route 53 domain name service, on the other hand, is used for the registration and management of our Internet domain.

What is the importance of AWS architecture?

The AWS architecture makes it possible to offer the best services to clients based on web services technologies, adding or removing virtual servers, the selection of services, etc. AWS services and resources are available worldwide 24/7 and 365 days of the year where solutions are easily deployed according to clients’ requirements.

Uses and advantages of AWS architecture:

  • Its feature of memory management makes it very fast and resilient for clients to host websites and get affirmative results.
  • Clients can scale up and down the resources according to their needs.
  • Clients can get more time to do their business tasks and leave the rest to AWS as AWS is fully loaded with advanced features to reduce workload.
  • It provides end-to-end security and privacy to its clients by ensuring the three pillars of security—confidentiality, integrity, and availability—of the client data.

Key Components of AWS Architecture

Here are the components of AWS cloud architecture

Load Balancing

The load balancing component of AWS architecture facilitates the enhancement of the application and the efficiency of the server. The hardware load balancer is generally used as a common network appliance in the architecture of traditional web applications to perform load balancing. But with AWS Elastic Load Balancer, the delivery of load balancing has become more efficient. Traffic is easily distributed to EC2 instances across various availability zones in AWS. The traffic is distributed to dynamic additions as well.

Elastic Load Balancing

Elastic Load Balancing

It can smoothly collapse or increase the capacity of load balancing by tuning a few of the traffic demands. Sticky sessions are also supported to achieve advanced routing services.

Amazon CloudFront

Amazon CloudFront

This component is mainly used for the delivery of the content on the website. The content can be of many types, such as streaming content, static or dynamic that are stored in global network locations. Users can request the content from any closest location in an automatic way, which ultimately enhances the performance.

Elastic Load Balancer

Elastic Load Balancer

ELB components become handy when the required traffic to the web servers needs to be delivered. It increases the performance greatly. Dynamic growth can be easily achieved through an Elastic Load Balancer. Based on various traffic conditions, its capacity can be adjusted.

Security Management

Security Management

AWS is mainly known for its secure environment where users can deploy their work without a doubt. It provides a security grouping feature. This is very similar to inbound network firewalls and ports, source IP ranges, and protocols that need to be specified to reach EC2 instances.



This tool is very handy in AWS when the memory cache needs to be managed in the cloud. In memory management, clearing cache plays a big role to help reduce the load on the server. Frequently used information is easily cached to increase scalability, reliability, and performance.

Amazon RDS

Amazon RDS

RDS stands for Relational Database. It offers services very similar to MySQL and Microsoft SQL Server and is very user-friendly and easily accessible.
